The One House Outside Tennessee - Yes, those are bunkbeds in a closet. My mom says people just can't stop talking about this part of the house when they get the tour. Why? Because it isn't normal, its amazing.
"Murphy bed" except it doesn't fold up to the wall; it remains folded out (the plane of the sleeping surface parallel to the ceiling) and travels on tracks up the wall-- so when not in use, the bed is stored in the ceiling.
